Takacs, James M. published the artcileCatalytic iron-mediated triene carbocyclizations: stereoselective five-membered ring forming carbocyclizations, Name: Allyldiphenylphosphine oxide, the publication is Journal of Organic Chemistry (1994), 59(23), 6928-42, database is CAplus.
The full details of studies into the regiochem. and stereochem. of Fe-catalyzed carbocyclizations of 2,7,9-decatriene derivatives to form five-membered carbocyclic ring systems are described. The sense and degree of simple diastereoselection depends upon the (2E/2Z)-alkene geometry. In general, (2E,7E)-trienes are the preferred substrate and give rise to 5-membered ring products in which the 2 newly ring formed substituents have the cis relative stereochem. E.g., treating triene I under the standard reaction conditions (dropwise addition of 3.1 equiv Et3Al to a cooled (0-5¡ã) solution of triene, 10-20 mol. % Fe(acac)3 and an equivalent amount of 2,2′-bipyridine in 10 mL C6H6 or preferably PhMe) gave > 80% cyclopentane derivative II. The roles of the allylic substituent, the alkene geometry, diene substitution, and the influence of resident stereogenic centers incorporated in the tether chain connecting the reacting 1,3-diene and alkene subunits are discussed.
